Missions from your space station require Dark Matter to unlock. Your alliance will need to contribute DM to the station until you have enough to unlock a mission. After the DM has been spent to activate a mission, you will need to contribute more DM in order to unlock the mission again.

The missions should appear in Mission section of the space station as soon as the station has been built. The individual missions will appear under the "Intelligences" tab until you have gathered enough DM to pay the Price of Intelligences, and click the "Detect" button. At that point the mission will become available under the "Missions" tab.
